Question

In an examination ,78% of the total number of students who appeared was successful. If the total number of failure was 176 and 34% gotfirst class. Find how many students were failed and how many students got first class?​

Answer 1

Step-by-step explanation:

let the total no of students be X.

% of total no of students who succeeded=78%ofX

total no of students who failed=176

% of no of students got first class=34%ofX

% of students failed=100%-78%=22%

22% of x=176

X=176×100/22

X=800

So,no of students hot first class=34/100×800

=272.
